on the core, orl the wire about the sleeve adjacent to pose may be woven, braided, formed of links connected together, or made in any other desired manner, but in the present instance I have made use of a braided wire mesh which is initially formed as a flat braid 10 wherein the strands 11 lie in close proximity to each other. The wire is first expanded, as shown at 12, by being forced over a mandrel 13, or by other suitable means which separates the strands 11 to form a more or-less loose mesh. After the braided wire has been expanded,-as shown, several layers thereof are sleeved over the core 2, a suiiicient length of the wire mesh being applied to the core to permit the same and a wire I4 may be wound about the structure to form a plurality of radial corrugations 15. After has been compressed in the direction of the length of the annulus and the surface thereof formed into corrugations by i the application of the wire 14, the ends of the ywire may be secured to each other or to the annulus andthe `wire retained thereon to permanently hold the wirel mesh in position may be removed and the corrugations formed by the wire will be substantially retained in the mesh after the removal of the wire. The free ends of the i tube and the various layers of Wire mesh may 1 y be secured together in any suitable or desired manner, and the free ends of the wire 14 may be secured together or to the tube in any suitable way whereby the wire 14 will be securely held in place.

The structure may be formed byfirst se# vcuring together the ends 3 and 4 of the core, `and then coVerinO the annulus with aplurality of layers of braided, woven, or linked wire mesh in .sheet or strip form which may -be wound therearound or applied in the form of spiral wrappings.

However,

VAthe structures shown in Figs. 4 and 5 `may be "formed by winding a sheet or strip of wire mesh into the form of a cylinder and then inserting the spherical core 16 therein and ap.- plying cord'svor wires 20 and 21 after the manner described.

WhatI claim is z- V1. Av scouring device comprising a core, a tubular wire mesh fabric, the strands of which are spaced from each other, said yfabric being sleeved over the core and providing a plu- `rality of circumferentially extending surface corrugations. f

.2. A scouring' device comprising a core, a wire mesh fabric sleevedover the core and having a plurality of surface corrugations, and a wire surrounding a portion of the wire mesh fabric and core and located between the corrugations for securing the Wire mesh-fabric to the cores.

3. A scouring device including, 1a ringshaped coreand a separate reticulated metalhc fabric enveloping said core, said fabric being of greater length than said core, Vthe surface of such fabric being disposed in the form of corrugations to accommodate the l entire length of such fabric upon said core.

4. scouring device including a sleeve of reticulated abrading metal, a-core disposed .within said sleeve being materially in excess of the length of said core .and the ends of isaid `sleeve being disposed substantiallyy adjacent the core ends, the .surplus material of said sleeve being disposed in theform of corrugations having their innermost portions in contact with saidfcore and said corrugations extending circumferentially of said core.

5. A scouring device including aV ringshaped core having its ends connected, an abrading metallic reticulated fabric tube member sleeved upon said core, the length of said fabric being normally in excess. of the major circumference of said core, the surplus fabric material being disposed in the form of corrugations around said core.

In testimony whereof I havev affixedV my signature.
